Solve and graph inequality

Answer:

The equation is y= 0,65 x

If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately  pays (y) is  the original price (x) minus a 35% of this price: y= x -0.35 x . By association: y= (1-0.35) x and then y= 0.65 x.

The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).

Step-by-step explanation:

The price without discount (or without the coupon) is x.

The price with discount (or with coupon) is y.

y and x are both related: y is a percentage of x, specifically, y is 35% smaller than x. This means that y =0.65 x.

Answer:

0.85x

Q1: 250

Q2: 50

Step-by-step explanation:

Q1: 14,000 + 160x = 24,000 - 200x

24,000 - 14,000 = 10,000

200x - 160x = 40x

10,000/40x = 250

Q2: 800 - 6x = 1,000 - 10x

1,000 - 800 = 200

10x - 6x = 4x

200/4x = 50

here ...

let us suppose breadth of the room be x.

then, length = 2x

now ,the cost of plastering the floor is RS 1080 at rate of RS 15 per ...

hence

the area of floor{length *breadth} =1080/15

x*2x=72

or,2x^2=72

or,x=√(72/2)

hence, the value of x= 6m

(ie. breadth {x}=6. &. length {2x}=12)

again....

we have ,

volume of the room (length *breadth*height)is 396m^3

12*6*height=396

72*height=396

height=396/72

hence , height=5.5

we know,

the area of 4 walls = 2( length+breadth)*height

=2(12+6)*5.5

=198

hence the cost of plastering 4 walls at the rate of RS 20 per SQ meter = 198*20=RS 3960

Answer: $14.40

Step-by-step explanation:

Full price = $18.00

20% discount of full price = $18.00 x [tex]\frac{20}{100}[/tex]

                                           = $18.00 x 0.2

                                           = $3.60

Price paid after 20% discount = full price minus 20% discount

                                                  = $18.00 - $3.60

                                                  = $14.40

Answer:

C ) 1/3

Step-by-step explanation:

In the given equation, y = 1/3x, where it represents a proportional relationship:

1/3 represents the constant of proportionality which shows that as x increases, y also increases at the same rate. The constant of proportionality in this given instance is also the rate of change, or the slope.

The constant of proportionality under the direct proportion condition is the slope of the line when plotted for two proportional constants x and y on a graph.

Therefore, the correct answer is C) 1/3.

Answer: Slope: 2/3

Plug the equation into y2 - y1 / x2 - x1 and you should have the answer!

m GHI = 82°

Step-by-step explanation:

59+39=98

180-98=82 <==== answer

180 is the total amount of degree

Answer:  36°  and 54°

Step-by-step explanation:

Let the larger angle be 'R' and the smaller angle 'q'

⇒       R + q = 90     [since complementary angles have a sum of 90°]

Then  R - q = 18   [since 1 of 2 complementary angles is 18 less than other]

We can combine the equation

(18 + q) + q = 90

     18 + 2q = 90

            2q = 72

               q = 36

We can solve for R

             R - 36 = 18

                    q = 36 + 18

                    q = 54

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

Given the linear function, x + 10 = y,

Its domain is the set of all real numbers, as represented in the interval notation, (-∞, ∞).

The same goes with range, the set of all real numbers, as represented in the interval notation, (-∞, ∞).

Answer:

y = -4x + 12

Step-by-step explanation:

Parallel lines have the same slope. Since the slope of the given equation is -4, then the slope of the other line parallel to it must be the same.

Using the slope, m = -4, and the given point, (2, 4):

Substitute these values into the slope-intercept form:

y = mx + b

4 = -4(2) + b

4 = -8 + b

4 + 8  = -8 + 8 +  b

12 = b

Therefore, the equation of the line parallel to  y + 6 = -4(x - 1) is:

y = -4x + 12

Answer:

4x-2

Step-by-step explanation:

Slope intercept form is y=mx+b, so get y on one side.

do the multiplication first -4(x-1) is -4x+4

Now move the six to the other side; y=-4x+4-6

Simplify, y=-4x-2

Answer:

a(x)= 3mx+4

The statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body.

We have some statements that describes how ultrasound can produce an image.

The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body to provide the information necessary to produce an image.

Therefore, the statement that best describes how ultrasound can produce an image is sound waves that form outside the body reflect off the body and are detected by the machine.

Step-by-step explanation:

The sum of an infinite geometric series is expressed according to the formula;

a 1 r where;

a is the first term of the series

r is the common ratio

If the sum of an infinite geometric series is three times the first term, this is expressed as

S∞ = 3a

Substitute S = 3a into the formula above to get the common ratio r;

Answer:

Step-by-step explanation:

We will first have to find the fraction of the whole land goats use. If we add 2/5 and 1/4, we will get 13/20. Simplifying the expression 1-13/20 gets 7/20, which is the total fraction of land the goat and sheep has. The goat will then get 7/20*1/7 of the whole land, which is 1/20. The sheep will then get 7/20*6/7 of the entire land, which is 3/10. Because 1/20 of the whole land is 12 acres, the farmer has 240 acres. SImplifying the expression 240*3/10 gets 72 acres

Answer:11 people

Step-by-step explanation:

Answer:

y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is. It can have either a positive or a negative value. When a standard form of a linear equation is of the form Ax + By = C, where 'x' and 'y' and 'C' are variables and 'A', 'B' are constants, the slope-intercept form is the most preferred way of expressing a straight line due to its simplicity, as it is very easy to find the slope and the 'y intercept' from the given equation.

Meaning of y = mx + b

y = mx + b is the slope-intercept form of a staight line. In the equation y = mx + b for a straight line, m is called the slope of the line and b is the y-intercept of a line. y = mx+b, where

y ⇒ how far up or down is the line,

x ⇒ how far along is the line,

b ⇒ the value of y when x = 0 and

m ⇒ how steep the line is.

This is determined by m = (difference in y coordinates)/ (difference in x coordinates). Note that difference in y coordinates is indicated as rise or fall and difference in x coordinates is indicated as run.
